To the Editor:—The article on "The Role of Dexpanthenol in Postoperative Ileus" (The Journal181:827 [Sept 8] 1962) is such an informative and valuable contribution that I hasten to congratulate you on the publication of this paper. Reports of this nature serve to maintain the high reputation of The Journal.The statistically semiliterate reader might be puzzled by the term "ridit." It would be helpful to readers like me if such technical terms could be explained (even in a footnote, in very small type) in future articles.The above letter was referred to one of the authors of the article cited, and he has submitted the following reply.
